This is why Frostytech doesn't test watercooling rigs very often, and never as individual components....

"Welcome to my review of The Feser Company (TFC) X-Changer 480ER radiator. This radiator would be of the "double thickness quad" sized radiator specifically designed for those that must have the absolute highest radiator performance with silent fan systems. First I would like to give special thanks to Martin from The Feser Company for providing me with a sample to test.

Check out their website for the latest developments in water cooling technology."
